Preflop: Do agree with your idea here to rather Call it. His line doesn't look like very weak either. Against some opponents I might even just fold the hand since at the best we might get a coinflip.Flop: Well, his Cbet size is kinda smallish, kinda indicates to weakness. Might even be some overcards.Turn: I'd very likely act according his bet size on flop and donk myself here to protect my hand vs overcards plus of course get some information where we stand with out hand. We don't want to see Check behind.

As playedRiver: Well, the problem is that what's his 3bet range? Most of the 3bet range did actually hit by river now. Most of the Ax hands and also there ain't gonna be that many bluffs in his range. Most likely it's even a Ax hand, I'd rather be inclined to fold. It's still 1/5 of our stack.
